Those shorts are pretty funny, personally i dont think i would wear them..

I rolled some no gi after doing exclusively gi for a few months, and i was suprised to notice the lack grips when working from the guard. Arm bars from bottom really suck no gi, as the guy just rips his arm out. Much better to go for sweeps and fight from top.

Its funny because when i first started grappling it was at a club that was almost all no gi, so i pretty much just did that. Then i moved to Oregon and joined Straight Blast and started doing more gi. At first i hated it because i couldn't move as fast but then i got a little more technical and now i prefer it. Offense is much harder without the gi. But i think it is important to train both.
